So it's mostly as I thought, then. We can only speculate (though said speculation going on here intrigues me). I had missed that line from Krile though. I wonder what kind of 'primordial essence' was being used, since I assume it's not all thanks to them having gotten their paws on Shinryu. I assume as much since I can only assume Zenos was already possessed of Resonance when we first met him.
